| 目的 探讨256层iCT血管造影诊断下肢动脉闭塞症(ASO)的诊断价值。方法 回顾性分析50例经DSA确诊的ASO患者50例,均行256层iCT血管造影,其后于两周内行DSA造影或治疗。以DSA为金标准,计算CTA诊断ASO的效能,计算与DSA评估血管狭窄分级的符合率。结果 共检测730段血管,CTA诊断ASO的敏感度、特异度、阳性预测值、阴性预测值和准确率分别为99.34%(453/456)、96.35%(264/274)、97.84%(453/463)、98.88%(264/267)和98.22%(717/730);CTA评估血管狭窄分级共686段与DSA相符,符合率为93.97%(686/730)。结论 256层iCT血管造影检查无创、方便,诊断ASO和评价血管狭窄程度准确率高,对制定治疗方案具有重要指导意义。 |

| Objective To evaluate the clinical value of 256 layers iCT angiography in diagnosing arteriosclerotic occlusive disease (ASO). Methods Totally 50 patients with ASO confirmed by DSA were retrospectively analyzed. All the patients underwent 256 layers iCT angiography and then DSA within two weeks after CTA. The diagnostic ability of CTA for ASO was asssessed with DSA as gold standard and the coincidence rate for assessing arteriostenosis degree compared with DSA was calculated. Results There were 730 segments were measured. The sensitivity, specificity, positive predictive value, negative predictive value and accurate rate of CTA in diagnosing ASO was 99.34% (453/456), 96.35% (264/274), 97.84% (453/463), 98.88% (264/267) and 98.22% (717/730) and the coincidence rate for assessing arteriostenosis degree compared with DSA was 93.97% (686/730). Conclusion 256 layers iCT angiography is safe and convenient, with high accuracy in diagnosing ASO and assessing the arteriostenosis degree, which have important significance in guiding the clinical treatment of ASO. |
